The purpose of this study is to determine the correlation of socioeconomic, dietary, and anthropometric-nutritional variables of parents and their children to overweight (including obesity) in schoolchildren in Santa Catarina State, Brazil. This is a transversal study conducted on 4,964, 6 to 10-year-old schoolchildren registered in 345 Santa Catarina elementary schools. The following data were acquired: the children’s current weight and height, birth weight and length, duration of breastfeeding, age at which water, herbal tea and other foods were introduced to their diet; parental income, education level, age, weight and height were also obtained. The prevalence of overweight and obese children were estimated by point and by interval with a 95% confidence; prevalence rates were obtained based on the Poisson model. An hierarchical approach was used, in which variables were adjusted within blocks and included in the model when they presented pEste estudo objetivou verificar a associação entre variáveis socioeconômicas, dietéticas, antropométrico-nutricionais dos pais e da criança e a presença de sobrepeso incluindo obesidade, em escolares do Estado de Santa Catarina. Trata-se de um estudo transversal com 4.964 escolares entre 6 a 10 anos matriculados em 345 escolas do ensino fundamental de Santa Catarina. Foram obtidos dados de peso e estatura dos escolares, peso e comprimento ao nascer, tempo de aleitamento materno, idade da introdução de água ou chá e de outros alimentos, renda, escolaridade e idade, peso e estatura dos pais. As prevalências de sobrepeso e obesidade foram estimadas por ponto e por intervalo com 95% de confiança e as razões de prevalência foram obtidas a partir do modelo de Poisson. Foi utilizada a abordagem hierárquica, onde as variáveis foram ajustadas dentro dos blocos e incluídas no modelo quando apresentaram p
